Module 2: Solving a Ratio Problem Using Multiple Representations  
### **Task Introduction**  
"Welcome to this module on proportional reasoning and multiple representations!  
Your task is to solve the following problem:  
**Jessica drives 90 miles in 2 hours. If she drives at the same rate, how far does she travel in:**  
- **1 hour?**  
- **½ hour?**  
- **3 hours?**  
💡 **We will explore different representations to deeply understand this problem.**  
💡 **I will guide you step by step—let’s take it one method at a time.**  
💡 **Try solving using each method first, and I will help you if needed.**  
*"Let's begin! We'll start with the first method: the **bar model**."*  
---
### **🚀 Step 1: Bar Model**
🔹 **AI Introduces the Bar Model**  
*"Let's solve this using a **bar model**. Imagine a bar representing 90 miles over 2 hours. How would you divide this bar to find the distances for 1 hour, ½ hour, and 3 hours?"*  
🔹 **If the teacher provides an answer:**  
*"Nice! Can you explain how you divided the bar? Does each section match the correct time intervals?"*  
🔹 **If the teacher is stuck, AI gives hints one by one:**  
- *Hint 1:* "Try splitting the bar into two equal parts. Since 90 miles corresponds to 2 hours, what does each section represent?"  
- *Hint 2:* "Now that each section represents 1 hour, what about ½ hour and 3 hours?"  
🔹 **If the teacher provides a correct answer:**  
*"Great job! You've successfully represented this with a bar model. Now, let's move on to a **double number line**!"*  
---
### **🚀 Step 2: Double Number Line**
🔹 **AI Introduces the Double Number Line**  
*"Now, let's explore a **double number line**. Draw two parallel lines—one for time (hours) and one for distance (miles). Can you place 90 miles at the correct spot?"*  
🔹 **If the teacher provides an answer:**  
*"Nice work! How do your markings show proportionality between time and distance?"*  
🔹 **If the teacher is stuck, AI gives hints:**  
- *Hint 1:* "Mark 0, 1, 2, and 3 hours on the time line."  
- *Hint 2:* "If 2 hours = 90 miles, what does that mean for 1 hour and ½ hour?"  
🔹 **If the teacher provides a correct answer:**  
*"Great! Now that we've visualized the problem using a number line, let's move to a **ratio table**!"*  
---
### **🚀 Step 3: Ratio Table**
🔹 **AI Introduces the Ratio Table**  
*"Now, let’s use a **ratio table**. Set up two columns: one for time (hours) and one for distance (miles). Try filling it in for ½ hour, 1 hour, 2 hours, and 3 hours."*  
🔹 **If the teacher provides an answer:**  
*"Nice job! Can you explain how you calculated each value? Do the ratios remain consistent?"*  
🔹 **If the teacher is stuck, AI gives hints:**  
- *Hint 1:* "Start by dividing 90 miles by 2 to find the unit rate for 1 hour."  
- *Hint 2:* "Once you find the unit rate, use it to calculate ½ hour and 3 hours."  
🔹 **If the teacher provides a correct answer:**  
*"Excellent! Now, let's move to the final method—**graphing** this relationship."*  
---
### **🚀 Step 4: Graph Representation**
🔹 **AI Introduces the Graph**  
*"Finally, let's plot this on a **graph**. Place time (hours) on the x-axis and distance (miles) on the y-axis. What points will you plot?"*  
🔹 **If the teacher provides an answer:**  
*"Great choice! How does your graph show the constant rate of change?"*  
🔹 **If the teacher is stuck, AI gives hints:**  
- *Hint 1:* "Start by plotting (0,0) and (2,90)."  
- *Hint 2:* "Now, what happens at 1 hour, ½ hour, and 3 hours?"  
🔹 **If the teacher provides a correct answer:**  
*"Fantastic work! Now that we've explored different representations, let's reflect on what we've learned."*

### **🚀 Summary of What You Learned**
💡 **Common Core Practice Standards Covered:**  
- **CCSS.MP1:** Make sense of problems and persevere in solving them.  
- **CCSS.MP2:** Reason abstractly and quantitatively.  
- **CCSS.MP4:** Model with mathematics.  
- **CCSS.MP5:** Use appropriate tools strategically.  
- **CCSS.MP7:** Look for and make use of structure.  
💡 **Creativity-Directed Practices Covered:**  
- **Multiple solutions:** Using different representations to find proportional relationships.  
- **Making connections:** Relating bar models, number lines, tables, and graphs.  
- **Generalization:** Extending proportional reasoning to different scenarios.  
- **Problem posing:** Designing a new problem based on proportional reasoning.  
- **Flexibility in thinking:** Choosing different strategies to solve the same problem.  
---
### **🚀 Reflection Questions**
1. **How did using multiple representations help you see the problem differently? Which representation made the most sense to you, and why?**  
2. **Did exploring multiple solutions challenge your usual approach to problem-solving?**  
3. **Which creativity-directed practice (e.g., generalizing, problem-posing, making connections, solving in multiple ways) was most useful in this PD?**  
4. **Did the AI’s feedback help you think deeper, or did it feel too general at times?**  
5. **If this PD were improved, what features or changes would help you learn more effectively?**  
---
### **🚀 Problem-Posing Activity**
*"Now, create a similar proportional reasoning problem for your students. Change the context to biking, running, or swimming at a constant rate. Make sure your problem can be solved using multiple representations. After creating your problem, reflect on how problem-posing influenced your understanding of proportional reasoning."*
